Autotransformer
PVAT3 40 - Discontinued items - no longer available
Characteristics
General data
The autotransformers of the PVAT3 series are used for voltage adjustment without the need for galvanic isolation and are manufactured according to EN (IEC) 61558-2-13. The transformers feature lower weight and a smaller form factor compared to other transformer types with separate windings.
Benefits
› Very high efficiency
› Excellent corrosion protection and low noise emission thanks to BLOCK IMPEX vacuum impregnation
› Short wiring time thanks to spring-loaded terminals
